Abdessamad Derraz e7aa9e870b fix: state libretro core versions from their code
Each libretro profile records version_basis and core_version is read
there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba
0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build
takes its version from git carry the nearest tag in describe form
(flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders
copied from .info files (Git, SVN) are replaced by the code's statement,
and a code that states none is null with kind none.

notes: |
FCEUmm (FCE Ultra mappers modified) is a NES/Famicom emulator forked from
FCEU Ultra by CaH4e3. FDS games require the FDS BIOS ROM (disksys.rom).
Game Genie emulation requires gamegenie.nes when the core option is enabled.
An external palette file (nes.pal) overrides the built-in palette when the
core option is set to Custom.
File path construction: src/general.c FCEU_MakeFName() joins the system
directory with each filename directly - no subdirectories.
